A method for determining at least one optical parameter of an eye of a person comprising displaying at least two sharp images on a retina of the eye of the person, the at least two images comprising a target and being carried by two light beams focused substantially in the plane of a pupil of the eye at at least two different positions, adapting a parameter of the target in each image based on feedback of the person relative to the change of the parameter of the target in the image, and determining the at least one optical parameter of the person's eye based on the adaption of the parameter of the target in each image.

Method for determining at least one parameter of an eye of a person

An eyeglass device including a variable transmission ophthalmic lens, a method for driving the transmission of such lens, and a non-transitory computer-readable storage medium for implementing such method. The eyeglass device comprises a light sensor configured for measuring an amount of light in the environment of a wearer and a controlling circuit configured for receiving at least light data from said light sensor and for driving the transmission of said ophthalmic lens on the basis of said light data. The controlling circuit is configured for driving the transmission of said ophthalmic lens on the basis further of movement data, said movement data being derived from an estimation of a movement of the wearer's head.

Eyeglass device and method for driving a variable transmission ophthalmic lens

A system for generating a virtual image for a wearer includes: a lens providing vision of a real scene and having refractive power related to the prescription of the wearer, a directive light source that emits directive light beams to create the virtual image, a reflecting element positioned on or in the lens that receives and redirects the directive light beams emitted by the directive light source toward a convergence area of an eye of the wearer, a dynamical optical element for modifying the received light beams, and a memory storing prescription data relative to the prescription of the wearer, the dynamical optical element modifying the light beams at the convergence area so as to compensate at least partly the prescription of the wearer.

A binocular device adapted to a wearer comprising: a first lens and a second lens, respectively designed to be placed in front of first and second eyes of the wearer, the first lens comprising at least a back face, a monocular display device designed and arranged to display a virtual picture towards the first eye of the wearer, the virtual picture being transmitted through the back face of the first lens defining a display area on the back face, wherein: the second lens comprises an adapted area and a corresponding area, the corresponding area is the area scanned by the second eye of the wearer when the first eye scans the virtual picture through the display area, and the adapted area is arranged so that the adapted area overlaps at least a part of the corresponding area, and the adapted area is configured to be obscured.

Binocular device comprising a monocular display device

A pictures positioning system and method for positioning pictures on display elements of a binocular displaying device is described. The binocular displaying device comprises a right and a left display element to be placed in front of corresponding eyes of a wearer, and to display right and left pictures. The binocular displaying device comprises a measurement means. The method comprises a providing step during which at least one wearer related parameter is provided, the providing step including a measurement operation. The measurement operation may be performed by using the measurement means embedded in the binocular displaying device. The method includes a display positioning determination step during which a right display positioning of the right picture on the right display element is determined and a left display positioning of the left picture on the left display element is determined. The display positioning determination step is performed based on at least one wearer related parameter.

Pictures positioning on display elements

A method for manufacturing an ophthalmic lens includes molding the lens () between a first mold portion (A) and a second mold portion (B) with the first entry surface (A) formed by making in the lens a molded cavity by means of a stud (C) secured to the second mold portion (B), and that the light guide () is temporarily secured to the stud (C) prior to molding. The second entry surface (B) is formed by making in the lens a molded cavity by means of a mold insert () temporarily secured to the light guide () prior to molding, the first mold portion (A) being placed above said insert ().

Method of manufacturing an ophthalmic lens for providing an optical display

The invention concerns a method of manufacturing a lens () that has a front face and a rear face, and into which light beams emitted by an optical element of a light beam generator system (IB) are introduced via an entry surface (Si) and directed towards the eye of the wearer to enable information content to be viewed, by means of a transparent optical insert (IA,A, I) constituted by a light guide, said insert (I) being with a form substantially identical to the form of a final lens suitable for being positioned in a frame () of a support. According to the invention, the method comprises the following steps: manufacturing said insert (I) with a form smaller than the form of said final lens according to a proportional transformation, manufacturing a lens blank (LB) by association of plastic material forming said front face and said rear face with said insert (I) and cutting said lens blank (LB) around said insert (I) and with a distance from the edges of said insert which is around 1 mm for at least 50% of the periphery of said insert.

Method of manufacturing a lens for providing an optical display

The invention provides an adjustment method for adjusting a binocular display, the display comprising for each eye of the wearer, an optical imager for shaping light beams corresponding to an image emitted by a beam generator device and for directing them towards each of the wearer's eyes so as to enable information content contained in a virtual image to be viewed, the display being associated with a pair of eyeglasses having two lenses supported by a frame. According to the invention, the method consists in moving at least one said lens (A,B) relative to said frame () with three degrees of freedom, in order to obtain superposition of the two virtual images, each said imager being contained in said lens (A,B) of said pair of eyeglasses.
